Yes I agree with you on me being a bit low on the Neem & Kelp. This was my first organic living soil mix and I was extremely low on funds at the time so I had to make do with what I could. I used the Build-A-Box from Buildasoil to get everything I needed in exact measurements. While it was technically more expensive when looking at buying things in bulk, it was much cheaper then buying 40-50lbs of amendments & unfortunately that was the option I needed at the time. So sadly I wasn't able to use a full cup of the Neem or Kelp in my original mix.
However I am planning on mixing up 202gal of soil here very soon as I am going to upgrade to 25gal pots. I will be using 10 25gal pots for now and get a cycle of 5 in Veg & 5 in Flower going. Soon after ill have another 10 25gal pots equaling 404gal of soil in total and ill go perpetual harvesting 5 25gal pots each month to two months depending on maturation times. The new mix will be much better as I am adding in the actual amounts I would have liked to start with in the beginning.
The "Base Mix" will consist of (per CF):
2.5gal of Bu's Blend Malibu Compost
2.5gal of Canadian Sphagnum Peat Moss
2.5gal of 3/8" Lava Rock
To that I will add:
1cup Acadian Seaplants Kelp
1cup Ahimsa Neem Cake
1/2cup Crustacean Meal
1/2cup Gypsum
1/2cup Pacific Shell Oyster Flour
4cups of Basalt Rock Dust micro-fines
I will top dress with Vermicompost as well as add a quarter pound of red worms to each pot to populate the soil and secrete the castings throughout the soil as they move around and do their thing. On top of the various other functions they provide by adding them to the container. I will water everything down w/ a Malted Barley tea, mulch with straw and after it cooks for about 3 weeks I will plant a cover crop of:
Barley - Haybet
Oats - Jerry
Flax - Brown
Buckweat - Mancan
Lentils - Indianhead
Safflower
Millet - Golden German
Hairy Vetch
Vetch Common
Millet - White Proso
Rape - Dwarf Essex
Japanese Millet
Clover - Medium Red
Clover - White Dutch
Clover - Crimson
I am also debating on adding 10% Bio-Char per CF
As far as the yellowing, it just happens with this specific cultivar. Even before switching to organics when using bottled nutes the yellowing was still present. There is only another two - two and a half weeks left before chop so I am not too worried about it as its to be expected. But I do agree strongly on the Alfalfa, though I apply it in teas rather than mixing in the soil. As I am more after the special microbes it contains which activate the soils microorganisms that help convert the 'nutrients' into soluble forms. Also going to try sprouting Alfalfa seeds for the PGR Triacontanol, but that will be further down the road.
The tea I am referring to I will only do once per cycle, usually before I switch to flower. Per 5gal of water I will add 1/2cup ground Alfalfa, 1/4cup Kelp meal & bubble it for 24hrs. To the finished brew before use I will add (per gallon) 1/8tsp of 200x Aloe Vera powder, & 2tsp of BioAg Fulpower Fulvic Acid. Then stir and apply as a soil drench. For newer soils or soils that are lacking this can be used
@half-full strength as often as once weekly perhaps alternating w/ a Neem/Kelp tea at the same amounts. Otherwise dilute the 5gal tea to whatever amount of water is needed.
But thank you for stopping by! I appreciate any and all input!
